Are you saying that the intensity didn't fall (refer to my post with images earlier) in a "negligible width" only on a very small scale? That when I look at the sides of an interference pattern (where sin⁡θ≈θ≈tan⁡θ is not true), the interference pattern does, in fact, dim?

I think this may have answered my question. Can you expand on that and hopefully use more logic, less equations (I am trying to understand why)? Thank you.

Thank you for the link of single slit diffraction. However, even if it does exhibit the properties of single slit experiment, the question is still not answered. In a single slit, the intensity in the middle is brighter, and the intensity falls as you move away from the center. The textbook is...

This is from the Tsokos Textbook. The textbook also says the width will never be negligible, but I am nonetheless interested in why it would work like that.

In our textbook, it says that the intensity of a double slit interference pattern stays the same if the slit width is negligible. I do not understand this concept. As far as I am concerned, intensity should decrease as the circle of diffraction increase, as intensity is work per area, and the...

Well, we've just started to learn electrical fields 2 weeks ago (I am in 2nd year IB HL Physics). I don't really know what a flux is either. I was just confused about how it is possible that the textbook/teacher says "there is no electric field inside a hollow sphere". But I guess this is a...

So whenever I add a charge inside the hollow conductor, the charge will be disrupted and an electric field will form? If yes, then when I add a positive test charge (electric field test) to the hollow sphere, shouldn't the test charge move? If that is the case, how can you argue there is 0...

"Now there is a field within the sphere due to the surface charge" So does this mean there can be electric fields inside a hollow charged conductor?

I know there is a lot of answers out there, but so far none really answered my question. Say I have this radioactive conductor sphere that has a negative charge. Of course, all the negative charges will be spread evenly on the surface and there SHOULD be 0 electric field inside the conductor...
